The blocklist consumer existed in the resolver library and the gateway, but the browser opened a flagged name without comment. Now the indexer process reads the subscribed lists from the chain every ten minutes and hands the flags to main. A flagged name loads a warning page naming the reason, the list and the report; the user may continue, and that is remembered per name. Two gates, because content is reached two ways. loadBns shows the real interstitial. serveBns refuses with an inline page on every path that skips it: reload, back and forward, bns:// links, web app windows. The inline page has no button, since a page at the site's own origin must not be able to approve itself; only blocked.html may ask to continue, checked by file URL. Settings › Naming has the policy: warn (default), never open, or ignore the lists. The csam reason is never offered a way through. A list that cannot be read keeps the last known flags and never stops a name from resolving. The gateway put its own warning in front of flagged sites, which this browser could not get past: it fetches files itself, with no cookie jar. It now sends x-bns-policy: client and the gateway stays out of the way for a client that says it decides for itself. dev/blocklist-selftest.js runs the real protocol handler and decision functions against a scratch profile. |

BNS — Namecoin-style decentralized names on Bitcoin Cash (chipnet)
A working prototype of "Option 3": names are CashTokens name certificates on the BCH chain (no fork, no sidechain), records ride in OP_RETURN, discovery via a beacon address, and the resolver is embedded in a wallet app with a built-in browser pane — the Brave/MetaMask-browser architecture in miniature.
See PROTOCOL.md for the on-chain design and its honest limitations.
Layout
src/lib/bns.js— protocol core: payload codec, chain indexer/resolver, tx builderssrc/wallet-app.js— wallet + embedded resolver + browser UI (npm run wallet→ http://localhost:4626)src/register.js/src/update.js/src/resolve.js— CLI equivalentswallets.json— chipnet seed phrases (TESTNET ONLY — never reuse for real funds)src/lib/gen-wallets.js— one-time wallet generation (already run)
Setup
npm install- Fund the wallet with free chipnet tBCH: go to https://tbch.googol.cash/,
paste the wallet address (shown in the app sidebar or by
node src/lib/gen-wallets.js), pick chipnet, solve the captcha. ~0.001 tBCH funds hundreds of registrations. npm run walletand open http://localhost:4626
Standalone resolver daemon (make EVERY browser resolve .bch)
src/daemon/bnsd.js— DNS server (answers*.bchfrom the chain, forwards everything else upstream) + HTTP gateway that serves on-chain sites by Host header. Test unprivileged:node src/daemon/bnsd.js --dns-port 5354 --http-port 8081, thennode src/daemon/dig.js hello.bch.setup/install.ps1— run from an elevated PowerShell. Installs the daemon as a boot-time scheduled task (SYSTEM, auto-restart) and wires the OS to it:- default (
-Mode nrpt): adds an NRPT rule so only.bchqueries reach the daemon; all other DNS is untouched. -Mode full: points every adapter's DNS at 127.0.0.1 (daemon forwards non-.bch upstream, ncdns-style); original servers are saved and restored on uninstall.
- default (
setup/uninstall.ps1— reverses everything (rule/adapters/task).
HTTPS for .bch: the "BNS Local Root CA" (created on demand in ca/, keep
root-ca.key private) signs per-name certs. The daemon's :443 gateway mints
them on the fly for locally-served names; node src/lib/issue-cert.js <name>
issues one for a real server (see the coinspectrum.bch nginx vhost). The
installer trusts the root machine-wide and enables Firefox's
enterprise-roots policy; cert fingerprints are published in "tls" chain
records for pinning.
Caveats: browsers with "secure DNS" (DoH) enabled bypass the OS resolver — disable it or add an exception; ports 53/80/443 must be free.
Try it
- Register
hellowith inline HTML (a website stored entirely on-chain), then typehello.bchin the address bar — the app resolves it from the blockchain (not DNS) and renders it. - Or CLI:
node src/register.js hello '{"h":"<h1>Served from the BCH chain</h1>"}'thennode src/resolve.js hello
